Application filed January 10, 1912. Serial No. 670,369.

hereby declare the following to be a full,

clear, and exact description of the inven tlon, such as will enableothers skilled 111 the art to which it appertains to makeand use thesame.

My invention relates to improvements in automatic feed mechanism formanually operated button setting tools and its object is to provide thesame with various new and useful features hereinafter more fullydescribed and particularly pointed out in the claims reference being hadto the accompanying drawings, in which Figure 1 1s a slde elevatlon ofmy devlce applied to a manually operated button set ting tool; Fig. 2the same with the various parts in position after the button has beenfed into the head of the staple setter the scale enlarged and partsbroken away to show the construction; Fig. 3 the same with the variousparts in position as at the close of the staple setting movement; Fig.4C the same as at the close of the first feeding movement; Fig. 5 adetailin section on the line 5-5 of Fig. 2; Fig. 6 a perspective detailof a part of the feeding mechanism.

Like numbers refer to like parts in all of the figures.

1 represents the upper jaw and 2 the lower jaw of amanually operatedbutton setting tool, respectively provided with handles or levers 1 and2 and pivoted to each other as at 3.

4 is a transverse head integral with the end of the upper jaw 1 in whichis a holding slide 9 to yieldably engage the fabric and hold the sameagainst the clenching anvil and retained within the head by a removablecap 5.

6 is a carriage slidable in the cap 5 in dove-tail ways on whiohcarriageis mounted the button feeding mechanism. The carriage and slide have alimited longitudinal movement controlled by a pin 23 fixed in thecarriage, extending through a slot 5 in the cap and into the holdingslide 9. The movement of the slide and carriage toward the jaw 2 isproduced by a spring 20 within the slide and abutting against the rearend of the cap 5 and the opposite movement by engagement of the slidewith the shoe and closing movement of the jaws. Fixed to the cap andclose above the holding slide 9 is a staple driver 8 consisting of astrip of flat steel recessed in the end to receive the eye of the buttonand to engage the crown of the staple to drive the same.

To receive and guide the button and staple a head 10 is fixed on the endof the holding slide 9 and provided with suitable grooves to guide thestaple and a slot to permit the eye of the button to pass there through.Projecting into the path of the eye of the button is a spring actuatedyieldable pin 19 which engages the said eye and stops the same withinthe rear end of the slot in the head 10. '11 is a clenching anvilmounted in the jaw 2 and engaged by the staple when driven through thefabric and against the same by the closing movement of the jaws. Toautomatically feed buttons into this head, an inclined button chute 12is mounted on the carriage 6 and provided wit-l1 the usual slot for theeye of the button and side grooves for the arms of the staples, beingprovided at the upper end with the usual means for attaching a supplytube loaded with said buttons and staples. In the bottom of this chuteis an opening within which projects the yieldable spring stop 24 to holdthe buttons from sliding down the chute and projecting through saidopening at each side of this stop is the bifurcated end of a pusher 13which feeds the buttons past this stop one at a time, as hereafterdescribed. This pusher traverses pin 15 and is held in contact therewithby a spring 21 attached .to the pusher at one end and traversing anupwardly extended rear portion of the carriage at the other end whichportion is provided with a projection or hump 22 which is engaged by thespring to stop the pusher after the first feeding movement thereof.

To depress the pusher and allow the same to pass the eye of the firstbutton, shoulders 18 are provided which engage the pin 15 and depressthe pusher.

14 is a yoke attached to the rear extension of the carriage embracingthe button chute and pusher and supporting the pin 15. This pin alsosupports the spring stop 24:.

shifted to and fro by contact with the arm? at the ends of the slot.

The normal position of the parts is shown in Fig. 2 with a button andstaple fed into the head 10 and held by the yieldable stop 19 the pusher13 being below the first button of the series and with the lever 16 incontact with the arm 17 at the inner end of the slot. As the staple isclenched by closing of the jaws the parts assume the position as in Fig.3 the driver 8 engaging the crown of the staple at each'side of the eyeof the button and driving the staple through the fabric against theanvil 11 carrying the "eye of the button past the yieldable stop 19.

At the same time the carriage and slide 9 are forced back, the spring 20being compressed. This moves the lever 16 rearwardly at its upper endcarrying the pusher back with the shoulders 18 under the pin 15depressing the pusher and carrying it with its lower end oppositethespace between. the eyes of the first two buttons.

As the levers 1 and 2 are released the spring 20 moves the slide 9 tofollow and open the jaw 2. Early in this opening movement the lower endof the lever 16 is carried against the arm at the inner end of the slotand moves the pusher sufficiently to bring the shoulders 18 out ofcontact with the pin 15. This permits the spring 21 to force the end ofthe pusher 13 up into the chute to engage the lowermost staple of theseries. The sliding of the shoulders 18 off the pin tends to move thepusher downward and to prevent it from prematurely throwing the buttonover the stop 24:. Thespring engagesthehump 22 and stops the pusher. inthe position shown in Fig. 4:. A further openingmovement of the. jawscarries the lever 16 again in ,contact with the arm 17 at the end oftheslot and this forces the spring 21 over the hump 22 and carries theeye of the button over the stop 2 1 whereupon the said .buttonand stapleslide down to place in the head 10 against the stop 19 ready-for arepetition of the operation described.

What I claim is 1. In combination with button setting tool, a slidingcarriage mounted on the tool and automatically moved thereby, a buttonchute mountedon the carriage and having an opening in its bottom, ayieldable stop projecting throughsaid opening and within the path oftheeyes of the buttons, a pusher also projectingthrough said'opening andmeans for reciprocating the pusher operated by. movement of thecarriage.
